Description

Technical Field

[0001] The utility model relates to the technical field of battery cabinets, in particular to an air-cooling heat dissipation device and a battery cabinet. Background Art

[0002] The energy storage battery cabinet is a centrally managed and controlled energy storage system, which is mainly composed of battery packs, battery management systems, charging management systems, energy management systems, fire protection systems, etc. Its main function is to store excess electrical energy and release it when needed to achieve the purpose of balancing the grid load, improving power quality, and improving emergency response capabilities.

[0003] Air-cooled energy storage battery cabinets are classified into two types, namely left-right air inlet and front-outlet and rear-right air inlet and front-outlet, depending on the structure of the battery box. Among them, the battery cabinet with left-right air inlet and front-outlet has an air duct arranged on the upper part, and the cold air from the air conditioner is introduced into the air duct of the battery cabinet, and then the cold air is directed downward to each battery plug-in box to dissipate the heat of the battery plug-in box. However, there is a situation where multiple battery plug-ins in the battery cabinet receive different amounts of cold air and different heat dissipation effects, and the temperature difference of the entire battery cabinet product will become larger.

[0004] In order to improve the overall heat dissipation effect of the battery cabinet, in the prior art, such as patent CN116526003A, a storage battery cabinet unit and a storage battery cabinet disclose that vertical air ducts are provided on both side walls of the battery cabinet unit, and an air duct inlet is provided on the top of the vertical air duct. Under the negative pressure of the exhaust fan, the cold air in the vertical air duct enters the battery box through the air duct inlet for heat dissipation of the battery box. On the basis of the traditional vertical air duct, a guide plate structure is added, and combined with the exhaust fan in the battery box, the overall uniform heat dissipation of the battery cabinet is achieved. However, each exhaust fan will introduce part of the cold air into the corresponding battery box. The battery box at the bottom of the vertical air duct obtains less cold air than the battery box at the top of the vertical air duct, which is not conducive to further improving the uniformity of the overall heat dissipation of the battery cabinet.
